(Cl. 11--l') L7 Claims.

This invention relates to amachine and method for making book construction, particularly oi the type in which a plurality of sheets are loosely bound together by means of a helicalor spirally shaped binder which passes through a rowV of registering openings forming a row of passages through a margin ofthe superposedsheets.

YIn previous devices used for binding books of the character described, Athe perforated sheets are in a horizontal position at the time the helical binder is to be introduced into the perforations. It is necessary to shift the sheets so that the rows of perforations in theY sheets willdeiine arcuate passagervays for the bindenand further, to secure the sheets in this position. This has involved the use of guides, clamps and Various movable means which are automatically operated. Accordingly, it is an object of this invention to provide a device for binding a plurality of marginally perforated sheets with a helical binder wherein the sheets are positioned vertical ly in a manner to properly arrangev the. sheets for the introduction of thevhelical binder intoY the perforations of the sheets without the usev of movable guides, clamps and the like.

Another object of this invention is to provide in a device i the character described, rneans for supporting a plurality of marginally perforated sheets wherein the supporting means is Xed and is further designed to so position the sheets that the perforations in the sheets will denne an arcuate passageway for the reception of a binder fed towards the supported sheets.

Still another object of this invention is to provide in a device oi the character described, means for frictionally feeding or threading a spiral binder into engaging relationship with a plurality of marginally perforated sheets positioned to receive said binder, wherein the feeding operation may become ineffective in the event that the binder jams or an obstruction in the perforations in the sheets, is encountered.

Yet another object of this invention is to pro! vide in a device of the characterdescribed, means for suspending and positioning a plurality or marginally perforated sheets in a vertical position, the said positioning means having curved hooklike portions which permit the perforations in the sheets to denne an arcuate passageway,

the positioning means further functioning as a bination cfa fixed guide means for an advancing sprial binder and means adjacent said guide for effecting the advance of said spiral binder longitudinally of said guide.

Other objects of this invention will in part be obvious, and in part hereinafter pointedv out.

The invention accordingly consists in the features of construction, combinations of elements, andarrangement of parts which will be exempliiied inV the constructionv hereinafter escrihed, and' of which the scope of application will he indicated in the following claims.

Fig. l2 is a iront elevational View, broken awat7 in part,` of the spiral binder. support shown in Fig. 11;

Referring now in detail to the drawing, it designates the device embodying the invention. The same` kcomprises a table il which includes a top member l2 of rectangular shape comprising an'upper surface I3, a lower surface ifi, and a front edge it. A centrally located portion of the edge I5 is formed'with a longitudinally eX- tending notch l B which includes a rearwardly inclined back wall il', for the purpose hereinafter described. The top member l2 is supported at a proper height by legs it, which are interconnected at their lowerk portions by side braces i9. The mid portions of the braces i9 are interconnected by an elongated member 2U which extends parallel to the top member I2.

Secured to the lower surface I4 of the top member I2 at the right hand end thereof, looking at Fig. l, is a downwardly extending bracket 2 I. Secured to the bracket 2I and extending outwardly thereof is a right angle motor mounting bracket 22 on which is mounted a motor 23 with its armature shaft 24 extending parallel to the length of the top member l2, and having secured thereto a pulley 25. A pair of spaced, similar, aligned bearing brackets 25, 2l are also secured to the lower surface I of the top member adjacent the front edge I5. J ournaled in the bearing brackets 26, 2l is a rotatable shaft 28, the right hand end of which extends beyond bracket 2l and has secured thereto a pulley 29. The pulley 29 is in alignment with the pulley 25 and is interconnected thereto by means of a belt 3i).

Secured to the elongated member is a bracket 3i to which is hingedly or pivotally secured a treadle member 32. Extending upwardly from the treadle member 32 is a link 33 which is connected to the rear end of a forwardly extending arm 35, the other end of which extends upwardly and outwardly to a bracket 35 which is journaled for pivotal movement on shaft 28. A spring 35 has one end thereof secured to the undersurface I i of the top member I2 and the other end is secured to -a rear portion of arm 34. The bearing bracket 35 further comprises a forwardly and upwardly extending arm 3'! to which is secured a bearing bracket 38. The bearlng bracket 58 lies adjacent the front edge I5 of the top member I2, and is further provided with a stop screw 38a which extends through the arm 3l and bears against the inclined wall I1, for the purpose hereinafter described. A rotatable shaft 39 is journaled in the bearing bracket 38 and has secured to a portion projecting on one side thereof a roller member 45. The roller member 40 comprises a core 4I and an outer` surface 42 of rubber or the like. The portion of shaft 39 projecting on the other side of the bracket 38 has secured thereto a pulley 43. A pulley 44 is secured to shaft 28 in alignment with pulley 43 and is interconnected thereto by a belt 45. It will be apparent from a consideration of Figs. 1 and 5, that the motor 23 imparts rotary movement to shaft 28 by means of pulleys 25, 28, which in turn imparts rotation to roller member 40 by means of pulleys 43, 44. The roller member 4D may also bemoved to and from a position adjacent the front edge l5 of the top member I2, by the use of the treadle member 32.

lOn the front edge l5 of the top member I2 there is secured an elongated trough shaped member 45. The member 45 comprises an upwardly extending wall 4l which contacts the front edge I5 of the top member and is secured thereto by means of screws 48 or the like. Extending upwardly and outwardly of the wall 47 are `a pair of similar walls 45, 55, symmetrically arranged with respect to the wall 4l, with wall 49 overlying an edge portion of upper1 surface E3 of top member l2. The member i6 extends from a point adjacent pulley 43 along edge I5 of top member I2, beyond the end of the top member I2.

Secured to a forward edge portion of the upper surface I3 and projecting beyond the front edge i5 is an elongated guide plate 5i The plate 5i is formed on its forward edge with regularly spaced rectangular shaped grooves 52 alternating with rectangular shaped ribs 53 which extend in an inclined direction of predetermined angularity between the upper and lower surfaces of the plate as shown in Fig. 7. The ribs `53 adjacent the roller 40 have lower portions 54 cut away to accommodate the adjacent circumferential portion of the rolle;` 4G. Mounted on plate 5I is a rectangular shaped plate 55. The forward edge of the plate 55 is formed with grooves and ribs similar to those found on plate 5I and are in overlying registry therewith. The plate 55 is secured to plate 5I by means of screws 55. Clamped between the elongated plate 5I and the overlying plate 55 are a pair of spaced, similar pins 55a which project beyond the edges of plates 5I, 55. Fixedly secured on the projecting portions of pins 55a is a cylindrical member 5l', the axis of which is parallel to the forward edge of plates 5I, 55 and circumferential portions of which Contact the ribs 53. From a consideration of Fig. 6, it will be noted that each of the pins 56 is clamped between plates 5I, 55 in alignment with a rib 53, for the purpose hereinafter described.

On the plate 5I there is mounted a pair of similar, spaced hook like members 58. Each hooklike member 58 comprises a flat shank portion 55 which is secured to the plate 5I by means of screws 55 or the like. Extending from the shank 59 is an arcuate portion 6I of a predetermined radius. The arcuate portion ISI has a substantially circular cross section and is formed with a groove 52 on the inner, uppermost portion thereof. As shown in Fig. 10, the groove 62 is coextensive with the extent of the arcuate portion of the member. The hooklike members 58 extend from the plate 5I at a predetermined angle to the edge thereof and are mounted so that the members are aligned with a groove 52 on the plate 5I. The arcuate portion 6I of members 58 has the same inclination from the vertical as the grooves 52.

The device described is adapted to form a bound book of the type shown in Fig. 2, which comprises a multiplicity of superposed sheets 'Iii (the topmost or cover sheet being shown in Fig. 2) which are formed with a row of registering perforations ll along a margin thereof which in turn receive the spiral or helical binder l2.

In using the device embodying the invention, the operator suspends a multiplicity of sheets '15a together with the cover sheets l5 having the usual marginal perforation on the hooklike members 58. From a consideration of Fig. l0 is will be noted that the sheets l5, ma hang freely in a vertical position on the arcuate portions 5I of the hooklike members 58 and further that rows of perforations ll in the sheets define arcuate passage- Ways corresponding to the arcuate form of the suspending element.

The spiral binder l2 in continuous lengths is placed in the troughlike supporting member 46 and the leading end of the binder is moved towards the xed cylindrical guide member 5l. As shown in Fig. 9 the diameter of member 51 is slightly less than the diameter of the helical binder I2 which passes over it upon continued movement of the binder l2 with respect to the member 5l, the leading end of the binder is threaded into the first groove 52 in plates 5I, 55. At this time, the operator steps on the treadle 32 which brings the rubber covered roller 45 into contact with the helical portion of the binder supported by the member 5l and positioned in the groove 52. The rotary motion of roller 45 will impart helical movement to the helical binder by reason of the frictional contact of the rubber cover 42 of the roller with respect to the supported portions of the binder. It is to be noted that the dimensions of the grooves 52 are such that the wire or" the bin-der will lie within the grooves yet move easily with respect to the walls of the grooves. The width of the ribs 53 corresponds to the normal spacing between the successive rows of perforations in the marginal portions of the book to be bound. The convolutions of the binder 'iii will pass on -either side oi the pins 56 which position the member 5l, inasmuch as pins 55 overly a rib 5s in plates 5l, 55 and therefore do not interfere with the movement of the binder. As the rotation of roller t continues to produce helical movement in the binder, the convolutions of the binder will be received in the grooves 52 of plates 5|, 53 and longitudinally guided thereby. When the leading end of the binder wire reaches the first hook like member 58, the wire will be received in the groove 52 in the arcuate portion Sl of the hooklike member and will pass through the passageway deiined by the row of perioraticns in the sheets suspended on the member 58, as shown in Fig. 10. It will be noted that the curvature of the arcuate portion El of the member 58 corresponds to the curvature of the wire in the helical binder l2. In the same manner, the inclination of the grooves 52 and the hooklike member 5B corresponds to the inclination of the convolutions of the helical binder. In this manner the introduction of the binder into passageways deined by the perforations in the sheets is made possible by the use of xed guide means for the helical binder and iixed guide means which properly position the perforated sheets.

The continued helical movement of the helical binder will bring the leading' end of the binder to the second hook-like member 58, after having passed through the intermediate rows of perforations in the suspended sheets. At the second -hooklike member 5d, the leading end of the binder is again guided by the groove 62 in the arcuate portion 6l of the member, in the manner previously described.

When the helical movement of the binder has extended to the point where the binder has engaged all the rows of perforations in the book, the operator releases the treadle 32 which moves upwardly by the action of spring 35, which in turn has the effect of pivoting the arm 37 thereby Inovi ing the roller @il out of Contact with the helical binder. This stops the helical movement of the binder and the operator then proceeds to out the binder at a rear portion adjacent the left hand edgeof the book. The projecting ends of the f binder are bent adjacent the edge of the book soy that the binder is retained in its position.

The movement of the roller llt towards the fixed member 5l may be limited by means of the stop screws da'which extends through the arm 3? of the bracket supporting the roller and bears against the inclined wail il. By suitably adjusting the screw 33a, the 'maximum pressure of the roller di? with respect to the wire coils of the helical binder may be determined. This feature also ermits adjustments in the feeding pressure in order to avoid jamming of the moving coil. It is to be noted that since the feed used is of the frictionaltype rather than by positive movement, the feed becomes ineiective in the event that the wire becomes jammed for any reason or if an obstruction in the perforations of the book is encountered.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use. The binder may be'cut and its ends bent by suitable means.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not Iin a limiting sense.
